MACHINE FOR COVERING WIRES, CABLES, &c., AND FOR MAKING TUBING' ANDCORD.

SPECIFICATION forming part of Letters Patent No. 441,808, dated December2, 1890.

Application led August 30, 1890. Serial No. 363,513. (No model.)

To all whom ii; may con/cern:

' Be it known that we, VERNON ROYLE and JOHN ROY LE, J r., both of thecity ot' Paterson, in the county of Passaic and State of New Jersey,have invented a new and useful Improvement in Machines for CoveringWires, Cables, &c.,and for Making Tubing and Oord, of which thefollowing is a specification, reference being had to the accompanyingdrawings.

This invention is especially applicable tothe covering of telegraphicconductors of various kinds, as wire or cables, with insulatingcompounds of a plastic nature or capable of re-` duction to a plasticcondition, but is also applicable to the covering of other bodies withsuch materials and to the manufacture of tubing and cord of suchmaterial.

A machine embodying our invention consists, generally speaking, of apress and a die of a form and size corresponding with those of theexterior of the covering or body to be produced, and when intended forthe covering of a wire or body or the manufacture of a tube it includes,also,a thimble or core corresponding with the exterior of the wire orbody to be covered or with the interior ot' the tube to be produced.

XVe will first describe in detail a machine for coveringtelegraph-cables embodying our invention, and will afterward point outits novelty7 in claims. l

Figure 1 represents a central longitudinal vertical section of themachine. resents a plan of the same, mostly in section, the sectionbeing taken in the line afan of Fig. l. Fig. 3 represents a horizontalsection of part ot' the machine in the line azof Fig. 1. Fig. et is aplan or end view of the die which gives form and dimension to theexterior of the body or covering produced by the machine. Fig. 5represents a transverse section of the machine, taken in the lineyg/ ofFigs. 1 and 2. Fig. 6 represents a transverse section in the line 13 13of Fig. 1. Fig. 7 is a face view of a plate which is interposed betweenthe body and head of the press. Fig. 8 is a transverse sectional viewillustrating a modification of the press-body. Fig. 9 is a plancorresponding with Fig. 8 of the press-body, partly in section in theline 12 12 of Fig. 8.

Similar letters of reference designate corresponding parts in all thefigures.

Fig. 2 rep-` A and g designate the press-body, consisting of thecylindrically-bored trunk having a feeding-hopperA, andB is the feed orpressure screw fitted to said trunk, said trunk and screw constitutingthe principal elements of the press, which is substantially like thepress represented in our Letters Patent No. 325,303, dated September 11885, and like other presses for similar purposes, except as to theprovision for heating and cooling it, which will be hereinafter fullydescribed.

O is the press-head containing the die D and the core E, the axis of thedie and the thimble or core being arranged in the same plane with theaxis of the press-body, but perpcndicularly thereto. This press-head issecured to the body by bolts a outside of the latter, passing throughlugs in the body and head. In order to provide for adjusting the saidhead with the axis of the die and core to receive the changeable die Dand is bored f through the opposite side in line concentrically withsaid die to receive the core-holder E', into which the changeablethimble or core E is represente-d as screwed at c, Fig. 1. This holderpasses through a stuffing-box l) on the opposite side of the head to thedie and is packed tightly around its exterior within said box by meansof compressible packing-rings c and a gland c. These packing-rings alsoassist in rigidly securing the core-holder E', yet permit itslongitudinal movement.

To provide for the adjustment of the thimble or core forward or backwardwithin or relatively to the die, the said holder is fitted with anexternally-screwed socket CZ, which screws into a female thread in thegland c. This socket is secured to the core-holder so that both movelongitudinally together by means of a split clamping-collar d', which isICO clamped tightly on the rear end of the diecore-holder Withoutturning it, the screwed socket cl `is fitted loosely to the holder andis attached to the clamping-collar d by means of a ring cl3, which issecured to it by screws d4, and which enters a `roove in the saidcollar. When the socket d is screwed into or out of the gland, it turnson the collar CZ and coreholder E', and so moves the said holder forwardo r backward without turning it.

In the machine represented, which, as hereinbefore mentioned, is forcovering cables, not only the thimble E is hollow, but also the ,holderE to permit the passage through them of the cable, the interior of thethimble being just large enough for thecable to pass through; but formaking tube a solid core might be substituted for thc hollow core orth'imble E.

vlnzeither .case the exterior of the core or thimblefmight be madetaper, and so may the entrance to the die, so that by the longitudinaladjustment olf vthe core-holder the annular space between the core orthimble and the dielmay be varied, :according to the required thicknessof the covering of the-cable or of the walls ofthe tube.

In order to provide for the substantial support ofthe core-holderEagainst the pressure ofthe plastic substance forced into the head C bythe press-screw, the head has constructed integral with it an internalsocket C', which projects into the cavity of the said head beyond thecenter thereof, as shown in Fig. l, and from the back of the said socketthere is a rib-like lprojection of the solid metal, as shown at c2 inFigs. 1 and v2 and in dotted Alines in Fig. 6, for the furtherand highersupv.portfof' the core-holder, the said projection e2 j being taperedupward, as shown by the dotted lines'in Fig. G, to permit the plasticmaterial to '.passmore freely over it behind the core and vinto the die.

The'die D is representedas fitted tightly into a socket or holder D forthe purpose of `facilitating the use of dies of different sizes, whichmaybe fitted to the same holder in -suchimanner as to beinterchangeable.

To `provide for the positive concentric adjustment ofthe die and core,we prefer to Amake the dielaterally adjustable relatively tolthe core,instead of making the core adjustablerelatively to the die, as hasheretofore .been done, because by that means we are enabled to supportthe core more rigidly against the lateral pressure to which it issubject 'and to preserve a tight joint between the adjustablecore-holder and the head at the base of said holder. Thisadjustment is provided for in the following manner: The baseofthe-die-holder D is flat and it has aflange f, which is beveled on itsouter side at an angle of about forty-five degrees to the base, as shownin Fig. 1, and in this beveledflange are notches f', as shown in Fig. 4.Theliat base of the said die-holder is supported upon or against theflat bottom or back of a recess f2 provided in the press-head, the saidrecess being wide enough for the adjustment of the die-holder in alldirections laterally therein.

Through the walls of this recess are screwed adj Listing-screws f3,which have such. an inclination-as to press upon the beveled outer faceof the flange f perpendicularly thereto. The screws applied in this wayserve the twofold purpose, rst, of holding the die-holder firmlyin placewhen all screwed up tight, and, second, of adjusting the said holder tobring the die concentric with the core by screwing outward one or moreof the screws and screwing inward another or others. By slackening allof the said screwsfs the die-holder is left free to be turned to bringits notches f opposite the screws, which permits the holder and the dieinit to be taken out whenever desirable.

To provide a jacket for the .heating `and cooling of the Vpress-bodyandthe screw .B'by the circulation through the press -body .of steam,Water, or other heating or cooling Huid, the outer shell A of the body,whiclris of castiron, has cored in itacirc-uitouspassage or jacket i,the inner walls of .which are .formed 'by a cylindrical bushing g,.ofdrawn-steelstiling, fitted and expanded into the shell A. Thesaidbushing,which contains the :boreto which the press-screw B is Afitted,,is .represented as also entering into andcentering a plate F betweenthe body and theheadC-and a cylindrical hub G, kbolted onto the back ofthe body by bolts h, the said hub G alsoserving another purpose, to behereinafter described.

'lhe jacket or passage t', as shown yin iFigs. l, 2, and 5, is formed inthe shell Aby a series of internal.annularflanges i', into which `thebushing lits tightly, and a longitudinal rib 712, connecting all of thesaid.flanges,.anopening '113 being formed through eachliange, first inone flange on one side of the lsaid rib-z'2 and then in the neXt {iangeon the other side of the said rib, and soonalternatelythrough the wholeseries, the inlet -opening being at i* near one end of the body, and theoutletopening being near the other end ofthe body, as shown in Figs.1,2, and 5. The-outlet-opening and outlet-pipe i are also shown in Fig.5. Near the outlet-opening therefis a partition l0, (shown in section,Fig. 5, and dotted in Fig. 2,) which only extends from the last flanget" to the end of the press-body, and which forms the end of the passaget', the only outlet from which is at the bottom at 5, as beforedescribed. l

For the purpose of draining the watervot condensation from the bottomsofthe `several annular channels between the flanges t" L" of the jacketwhen steam is used as a heating medium, we make holes through theseveral flanges near the bottoms thereof-andinsert through the saidopenings a horizontal pipe o, (see Figs. l and 5,) which is open-along Aits bottom. Through this pipe all the channels are drained into thatonefin which the outlet is situated. To drill the said holes in theflanges t' and insert the pipe o, aflole IOO IIO

4- hole is lugged n with a screwlu T o as P er D D s i y val ves.

shown in Fig. 1. The heating or cooling fluid arrives at the inlet i4through a chest I, bolted by bolts I onto the top of the shell A. Thischest is shown in section in Figs. 1 and 3. It has two compartments jj', the former for heating fluid, as steam, and the latter for coolingfluid, as water, the separate fluids being supplied to the respectivecompartments by pipes j* jl, furnished with stop- The two compartments jj are in communication with each other by lateral openingsj2 jz* intheir partition, and from the Aopening t7'2 is a passage la to thejacket-inlet "i4, as shown in Fig. 1, which will conduct either theheating or the cooling fluidinto the jacket, according toiwhich of thestop-valves in the pipes j* j'* is open. This construction of thepress-body with a passage in the interior of the shell and a bushingwhich forms the inner wall of said passage and combines with saidpassage to form a jacket enables the said wall of the jacket which isnext the bore and feed-screw to be made much thinner than is possible ina press-body in which the jacket and bore are cast integral with theouter shell, and therefore the said construction 4enables Vthe heatingor cooling fluid to be brought as near as practicable to the compoundthat is being worked in the press, with the result that any changerequired in the temperature may be morequickly effected.

From the opening j2*, before mentioned, in the chest I (see Figs. 1 and3) there is a passage la', which communicates through a passage 7a2 (seeFigs. 1 and 5) in the press-body A with a concentric annular groove Z(see Figs. 1, 2, and 7) in the face of the plate F, hereinbeforedescribed as interposed between the press-body A and head C, the saidgroove serving the purpose, in whatever position the head is turned, ofconducting the heating or cooling fluid to the jacket m fm', which isprovided in the press-head C for the circulation of such fluid, whichpasses from the said groove tothe said jacket through a hole 7e3 (seeFig. 7) provided in said plate within said groove and communicating withthe upper compartment m of the jacket m m of the press-head, the twosaid holes being always kept in register with each other by alwaysshifting the plate F with the press-head C.

The jacket-m m of the press-head is divided into two compartments by atransverse partitition m2, which also extends into the removable bonnetC2 which is provided on said head. The heating or cooling fluid entersthrough the hole 7c3 into the upper compartment m and passes thencethrough an opening m4 (see Figs. 2 and 6) inthe partition m2, whence itmakes its exit through ahole 7a4, which is shown in Fig.' 7, and whichhas its position dotted'in Fig. 6, into a second concentric annulargroove Z in said plate, which groove is always in communication througha passage 705 in the press-body (shown in section, Fig. 5, and in dottedoutline in Fig. 2) with an outlet-pipe k7.

" For driving the screw B the said screw is prolonged in the form of ashaft B and projects through the press-body and through the fixed hub G,before mentioned as bolted to the latter, and a spur-gear J ordriving-pulleyis fitted to turn freely on the said hub and connectedwith the said shaft by a clutch H, which is fast upon the shaft andengages between the spokes of the gear or pulley. The gear or pulley iskept in place on the fixed hub G by means of an annular plate or collarL, of larger diameter than said hub, which g is bolted to the said hubby the same bolts h.

which bolt the said hub to the press-body. This collar L serves as athrust-bearing for the screw B, the thrust being received from ashoulder n on the screw-shaft IB through steel washers n fn?, insertedinto a counterbore in the hub G between the said shoulder and thethrust-collar L. Three washers are represented.

The above-described provision for driving and receiving the thrust ofthe press-screw relieves the screw of the weight of the gear J ordriving-pulley, which is necessarily large and heavy, and it providesfacility for changing the screw when necessary, as when the nuts aret-aken olf from the bolts 7L the screw can be withdrawn through the hubG, the thrust-collar coming with it.

In Figs. 1 and 2 there is shown an oil-box p, from which branch passagesp are provided leading through the hub G for the lubrication both of thegear or pulley .l and of the thrust-bearing and its washers.

It it should be desired to use the machine to make a simple` cord, thecore and coreholder may be removed, and the opening through which thecore -holder enters the press-head may be closed by any suitable means.

In the modification of the press-body shown in Figs. 8 and 9' the`circuitous passage between the shell A and the bushing g consists ofplain flanges el', cast on the interior of the shell and having each asingle opening i3 through it, the said opening being in the upper partof one flange and the lower part of the next one through the series, asmay be understood by reference to the said figures. In this'example theinlet is at t* and the exit at i5, as in the first-described example,and the passage 7a2, leading to the head, instead of being cored out, asshown in Fig. 2, fis made by a pipe, as shown in Fig. 9.

The circuitous passage provided in the press-body for the heating orcooling fluid by either of the constructions herein shown and describedcauses a much more uniform heating of the bore of the cylinder and itscontents than a simple jacket formed by two plain cylinders, one Withinthe other, as has been common in such apparatus.

It may be here remarked that thc plate F IOO IIO

.walls of said recess and pressing on `the'bev` is only made separatefrom the press-head C as a matter of vconvenience Vfor the construcvtion of the passages in and through it vwhich could not be so=easilymade in the'head itself; Abut the said ring, being always shifted Withthe head C kand never changing its iposition yrelatively thereto, `is toall intents fand purioses a partof thezhead.
